Title: Two-component developer and image forming method
Inventor: ASAHINA YASUO
IPC: G03G9/113
Filed: 1998-01-09
Abstract: PROBLEM TO BE SOLVED: To improve the characteristic of toner and carrier after preserving developer for a time, to prevent a machine from being soiled and to form a stable image for a long time by removing a separation member in a storage container so that the toner and the carrier may be mixed to be two-component developer, and supplying the developer to a developing part in the case of using the developer. SOLUTION: The developer container 1 is partitioned to two chambers by providing the separation member 4 in the center. The carrier 2 is stored in either chamber and the toner 3 is stored in the other chamber respectively. In the case of using the developer, the member 4 is removed, the carrier 2 and the toner 3 are mixed, and the container 1 is completely shaken and put into the developing part of the machine. By mixing the toner 3 and the carrier 2 just before setting the two-component developer in the developing part of the machine, the electrified amount (Q/M) of the developer is prevented in advance from being lowered with the lapse of time so as to eliminate failure caused by the lowering of the Q/M. It is good to set the particle size of the toner 3 to 3-10 μm and the particle size of the carrier 2 to 30-65 μm.

Title: Production of optical waveguide
Inventor: SAWA SHINNOSUKE
IPC: G02B6/134
Filed: 1984-01-13
Abstract: PURPOSE:To obtain an optical waveguide having a desired pattern in bulk glass without using means for mechanical positioning and joining of parts by rearranging a refractive index distribution by thermal diffusion in an electrolyte contg. the ion included in a substrate. CONSTITUTION:A thin film pattern 1 of silver is manufactured on soda glass 2 by a photolithography and aluminum 3 is deposited by evaporation on both surfaces of the glss 2. After the prescribed temp. is set, electric current is passed for specified time to migrate Ag<+> to the inside of the glass. More specifically, Na<+> of 12.8wt% Na2O existing in the soda glass and the Ag<+> are subjected to an ion exchange. The current is stopped and the aluminum silver foil on both surfaces of the glass plate is removed. When the glass plate is dipped for prescribed time in a molten NaNO3 liquid, a max. value arises in the concn. distribution and this max. value decreases with lapse of time. The Na<+> of the NaNO3 liquid and the Ag<+> are subjected to the ion exchange on the front side of the glass plate with the peak as a boundary and the Ag<+> is diffused into the molten liquid and the Na<+> is diffused into the glass thus the Ag<+> concn. decreases. The refractive index distribution is thus rearranged to the shape approximate to an ideal square distribution by which the waveguide is obtd.

Title: Method for improving characteristic of high temperature solid electrolyte fuel cell
Inventor: MORIMOTO KIYOYUKI
IPC: H01M8/04
Filed: 1992-01-14
Abstract: PURPOSE:To improve the characteristic or a high temperature solid electrolyte fuel cell (SOFC). CONSTITUTION:A power source (S1) different from an SOFC (S2) is used to feed the current, which flows in the direction reverse to the direction at the time of generating power, to the SOFC (S2). Consequently, a flow of the oxygen ion moving from a Ni-YSZ fuel electrode to an air electrode through a YSZ electrolyte film is generated to deoxidize Ni oxide of Ni-YSZ, and the ohmic resistance and the polarization resistance of the SOFC is reduced. Characteristic of the SOFC can be improved under the condition that the SOFC is set in a system. Characteristic of the SOFC deteriorated by the long term operation can be restored to prolong the lifetime thereof.

Abstract: PURPOSE: To provide simple construction of not using electric motor and the like and make the same compact by extending photographic lens in the focus control direction by a cooperating member provided to the lens barrel portion with the spring member having been energized by a manual energizing part.  
     CONSTITUTION: An endless rope 12 is moved clockwise by manually operating a slide knob 8 to energize coil springs 17, 17. In their energizing positions, a rope 12 is detained and held by the detation of a hook metal 19 and hook lever 20. At the same time, a photographic lens 4 is localized in the infinity position by cam plate 15. Depression of a shutter button causes a solenoid 12 to actuate and release the detention of the hook metal 19. While the rope 12 is turned counterclockwise by the energizing force of the coil spring 17 to let the cam plate 15 extend the lens 4 in the short distance direction, a detecting lever 33 also moved and rotates a cam 36 to oscillate a moving mirror 28, whereby focusing operation is accomplished. The focusing signal causes a solenoid 37 to actuate and cooperatively actuate a detention lever 38 to dtain and stop the saw tooth part 39 of the detecting lever 33. As a result, the rope 12 stops, the extension of the lens 4 stops and a shutter release SW 40 goes ON.
